When a substance evaporates, it gains energy.
yes
Electrons are both gained and lost. Electrons are both gained and lost.
They are gained.
evaporation should be exothermic because high energy molecules escape the liquid and low energy molecules are left behind.as k.e is directly proportional to temperature so we can say that heat is released during this process.....thus,it is exothermic.
no se
It's lost as thermal heat to surroundings.
no
Vaporization is an endothermic process. It takes energy to heat up material to the point that it vaporizes, so energy is gained by the material being vaporized and lost by the environment.
Condensation is exothermic. Energy is released during condensation. Energy can not be "lost" but merely change from one form to another.
no
it depends on conversion. wind to wind energy. Sun to solar Energy. and water to hydro have no loss only gained but on other hand electric to heat energy like also some heat will be lost. in nuclear energy some energy also lost during conversion.
give out energy
Kinetic Energy is gained in the foward changes and lost in the reverse changes of state
The liquid is evaporated.
It should be noted that energy cannot be gained or lost due to energy conservation. But there is a bit more to this as regards the situation being asked about. In terms of the energy of the water vapor, yes, the water vapor has more energy after it has evaporated. It has to have to have evaporated. The water vapor leaves the water from which it came with less energy; it took energy with it to evaporate. Either way, energy has been transferred from the body of water to the water that is evaporating, and it might help to view what is happening in that light.
i think impurities is the answer
The amount of energy that is lost or gained by the products during the reaction.
There is never an increase or decrease in energy, energy cannot be lost or gained. On the other hand, gas is at a higher level of energy than liquid. In other words, water, when condensed from water vapor, is lower in energy than the vapor it was condensed from.
